Specification of Letters Patent. Application filed September 25, 1911.

Patented Nov. 12, 1912. Serial No. 651,310.

To all whom it may concern Be it known that I, Janus L. Goon- KNIGHT, a citizen of the United States rcsiding at Lincoln, in the county of Logan and State of Illinois, have invented certain new and useful Improvements in Gear- Boxes for Awnings, of which the following is a specification, reference being had to the accompanying drawings.

is invention relates to improvements in gear boxes or housings for awnings and has for its primary object to provide means whereby the gear box may be easily and quickly attached to or removed from a base or supporting plate fixed to the wall or other permanent support.

Another object of the invention resides in the provision of a device of the above character consisting in its essential features of two elements whereby the gear box. or housing may be rigidly mounted and is at the same time susceptible of easy and quick removal from its support.

A further and more specific object of the invention is to provide a base plate for attachment to the wall having a longitudinal slot therein, a gear box provided with oppositely extending projections to extend behind the plate, a supporting lug formed upon said plate at one end of the slot and provided with a bolt recelvlng opening to receive a stud bolt carried by the box whereby said box is rigidly held in position upon the plate.

With the above and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings in which- Figure 1 is a front elevation of a gear box and mounting therefor embodying the present invention; Fig. 2 is a Vertical section thereof taken on the line 22 of Fig. 1; Fig. 3 is a transverse'section taken on the line 33 of Fig. 1; and Fig. 4 is a rear face view of the wall plate.

Referring in detail to the drawing 5 designates a wall or supporting plate which is secured to the face of a wall or. other structure by means of a plurality of screws 6. The edge portion of this plate lies closely against the face of the wall while the remaining portion thereof is spaced from the wall. This spaced body portion of the wall I l l l plate is provided with a central longitudinally extending slot 7, the upper end of which is laterally extended or widened as indicated at 8. The edges of this slot are also provided with notches or recesses 9 intermediate of its ends and an inwardly extending supporting lug 10 is integrally formed upon the rear face of the plate adjacent to the lower end of said lug. This lug is preferably provided with an opening 11, the purpose of which will be clearly disclosed in the following description.

The gear box or housing indicated at 12 is preferably, though not necessarily, of circular form and is open at one end. The edge of the annular wall of the gear box is adapted to engage closely with the face of the wall plate 5 and upon this annular wall at diametrically opposite points the projections 13 are formed. These projections are provided with reduced lateral extensions 15 whereby recesses 16 are formed between the projections and the edge of the annular wall of the gear box.

Upon the inner face of the wall plate 5 the gear or pinion supporting disk 17 is arranged, said disk having an opening 18 therein which is of substantially equal diameter to the width of the slot 7 in the wall plate. The outer closed end of the box or housing 12 is also provided with an opening 19. The chain operating gear or pinion 20 is arranged within the box 12 and is provided with the reduced cylindrical hubs 21 projecting from opposite faces of said pinion. Oneof these hub portions of the sprocket pinion is disposed through the slot 7 of the wall plate and mounted in the opening 18 of'the disk 17 while the other of said hub portions is rotatably mounted in the central opening 19 of the gear box 12. This latter hub portion of the sprocket pinion is provided with a rectangular socket 22 to receive the similarly shaped end of the crank handle which is adapted to be removably connected to said pinion. The annular wall of the gear box is also provided with open ings indicated at 12 for the accommodation of the operating chain. In the assemblage of the parts, the wall plate is securely fastened in position and the lugs or extensions 15 on the upper and lower portions of the annular wall of the gear box are dis posed through the extensions 8 of the slot 7 and the recesses 9 which communicate with Having thus described the invention what is claimed is z 1.

The gear box is then moved downwardly, the lugs 15 thereof extending upon the inner face of the wall plate and moving upon the edges of the slot 7 therein. In the lowermost position of the gear box, the stud bolt 11 carried thereby is disposed through the opening in the lug 10 whereby said gear box is supported in position and held against lateral movement with respect to the wall plate upon which with respect to the plate. the same is mounted.
